Seeding-roll.



UNITED STATES PATENT OFFICE.

GOTTHOLD L. LANGER, OF SAN FRANCISCO, CALIFORNIA, ASSIGNOR 'I'O ANDERSON, BARNG-ROVER MANUFACTURING COMPANY, OF SAN JOSE, CALIFORNIA SEEDINGr-ROLL.

Specification of Letters Patent.

Patented Apr. 23, 1912.

To all whom it may concern:

Be it known that I, Go'r'rHoLD L. LANGER, citizen of the United States, residing at San Francisco, in the county of San Francisco and State of California, have invented a new and useful Seeding-Roll, of which the following is a specification in such full and clear terms as will enable those skilled in the art to construct and use the same.

This invention relates to a roll used for the purpose of seeding fruit.

An object of the invention is to produce a roll which may have the pins thereof easily renewed when they are bent out of shape.

Another object of the invention is to produce a roll which may have the pins at any given place renewed without displacing more than one-third the total number of pins on the roll.

In the drawings, in which the same numeral of reference is applied to the same portion throughout, Figure 1 is a side elevation of one of the rolls, showing a portion of the pins and rings in place; Fig. 2 is an end elevation of the roll showing a portion of the pins in place; Fig. 3 is a view of the roll. partly in section, illustrating the manner of separating the roll parts when the pins at any given place are to be renewed; Fig. 4 shows one form of ring and pin set therein, and Fig. 5 shows another form of ring and pin set. In Fig. 6 the pins are twisted a small amount to prevent the ends of individual staples from presenting lines across the roll parallel to the axis thereof, and to make the distance between the individual pins more nearly the same.

The roll comprises a shell 1, having an annular ring 2, a cylindrical shell 3, having flanges 3 which fit into a groove in the shell 1, a shell 4, which latter forms the opposite end of the roll. The shell 4 has an annular ring 5 similar to the ring 2. The shell 1 is provided with a boss 6 into which the shaft 7 is secured. In the end of the shell 1, away from the boss 6, there is a spider 7, said spider being threaded to take a bolt 8. The shell 4 has a boss 9 into which a hollow shaft 10 is forced tightly, and to secure the several parts of the shell together the bolt 8 is provided with a bolt head 11, which bears on the end of the hollow shaft 10, thus drawing the parts 1, 3 and 4 tightly together.

A suitable pulley 12 is secured to the shaft 7, and the roll is supported by boxes 13 and 14, the latter of which is far enough away from the end of the roll to allow the part 4 to be moved away from the part 3, to allow the latter to be removed from the roll without disturbing the rings carried thereby.

The pin-holding rings are annuli, having radial grooves therein, as shown at 15, and the pins are staples which are pushed over the rings, each staple beingset in one of the radial grooves. It will be noticed that the rings may be grooved on one or both sides, as may be desired. When the sections of the roll have been tightened together by means of the bolt 8 it becomes necessary to tighten the rings against eachv other, and this is accomplished by means of the annular ring 17 and the set bolts 18, the latter of which are threaded in the annular ring 2 on the shell 1.

It will be noted that the shell is divided approximately into thirds, the object of which is to avoid the necessity of displacing all of the rings from the shell, which carries them, when it is desired to replace any pins. For example: Suppose a series of pins near the left hand end of the roll, Fig. 3, was injured. The bolt 8 would be removed, the shell 4 moved toward the box 14, and the shell 3, with its series of rings, would be carefully removed from the machine bodily. The remaining third of rings on the shell 4 would then be taken off, and the new pins inserted as desired. The same operation might be repeated with the shell 1 or 3 at will.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is as follows:

1. In a raisin-seeding roll, a roll shell formed of several sections, a hollow spindle and a bolt passing through said hollow spindle and securing the several sect-ions together, a series of annuli and a series of staples carried by said annuli, forming a substantially uniform pin surface, substantially as described.

2. In a fruit seeder, the combination with a drum, of U-shaped pins mounted thereon, each with its sides normally separated to form an intervening space into which the meat of the fruit is pressed, the bights of the pins resting against the drum, and means extending circumferentially around the drum and through said bights and occupying the lower portion of the space between the inner sides of the pins for supporting the pins radially with relation to the drum.

3. In a raisin-seeding roll, a roll shell having a journal to support it, a plurality of U shaped pins mounted thereon, annuli extending circumferentially around the roll and through the bights of the pins for supporting them radially with relation to the drum, and means whereby the entire series of annuli may be tightly forced together, substantially as described.

4. In a raisin seeding roll, a roll shell, a

, plurality of U shaped pins mounted thereon,

annuli extending circumferentially around the drum and through the bight-s of the pins for supporting the pins radially with relation to the roll, a heavy annulus at one end of the roll, and set screws bearing upon said heavy annulus to tighten the series of annuli against each other, substantially as described.

a bolt passing through said hollow spindle to secure the several sections together, a series of annuli, and a series of pins carried by said annuli and forming a substantially uniform pin surface, substantially as described.

In testimony whereof I have hereunto set my hand this 11 day of Nov. A. D. 1909, in the presence of the two subscribed witnesses.

GOTTHOLD L. LANGER.
